Ground Circuits

WARNING: This page is about a different car, the 1997 Hyundai Elantra. However, it is still accessible from the selected car via links, so may be relevant.
  1. Turn ignition off. Using a DVOM, check continuity between chassis ground and ECM ground terminals. See GROUND TERMINAL IDENTIFICATION table. DVOM should indicate zero ohms. If resistance is not as specified, check and repair circuit between ECM and ground.
  2. Connect voltmeter negative lead to chassis ground. Connect positive lead to each ECM ground terminal. See ECM GROUND TERMINAL IDENTIFICATION table. With engine running, voltmeter should indicate less than one volt. If voltmeter reading is greater than one volt, check for open, corrosion or loose connection in ground circuit.
